Multi-Stimuli-Responsive\nSupramolecular Polymers Based\non Noncovalent and Dynamic Covalent Bonds

Abstract

Several modes of\nsupramolecular assembly relying on noncovalent\nas well as dynamic covalent interactions were combined in a single\nmolecule. The supramolecular self-assembly of <b>1</b> can be\ncontrolled by three stimuli, namely light, pH, and addition of metal\nions, in both organic and aqueous media. The multi-stimuli-responsive\nnature of <b>1</b> was used successfully for the controlled\nencapsulation and on-demand release of hydrophobic molecules, such\nas dyes and drugs.
